Thinking of lowering my Focus....

peter212693 · 9 Apr 2007 at 19:41

Hi all

Ive had my eye on a set of Eibach Pro Springs, now I have herd that lowering a car it will suffer from excessive rear wheel camber, which wears tyres on the inner edge. Is this true and if so ive seen these about; Eibach Camber Adjustment Bolts for the rear. I take it its worth grabbing these aswell??

Cheers guys

i had some eibach lowering springs on my last focus, adverse tyre wear was not a problem.

How does the camber change with smaller/different springs ??? Does this happen with all lowered cars ??

It was on the owners club that all focus' suffer from it apparently

Usually those bolts are reserved for the fronts.

Surely if the car's geometery (sp?) is set up right then it shouldn't be a problem what so ever? As you could have the tyres touching the floor exactly as before, but the car is just lower? :confused:

No, it depends on the suspension design.

If the spring length is what keeps the camber at a set amount when resting, shortening that spring will make the camber rate increase. Lengthening the spring would actually force the camber to become positive.

I see, is there many cars like that? I know Scoobs are reliant on camber bolts for adjustment, nothing to do with the size of the spring/strut.

I'd go so far as to say that 99.9999999% of road cars have suspension geometries that cause camber change under bump and droop. Without some very sophisticated linkages it's simply inevitable.

Rear fully trailing arms are an exception of course!

Yes, but if you were to stick a really really short spring set on to your car the camber would be noticabley out but adjustment could be retained by the camber bolts. Even then, adjustment can not be enough to correct the angle.

ScoobyDoo69 · 10 Apr 2007 at 00:04

Is this then not what camber bolts are for? To allow further adjustment?

agw_01 · 10 Apr 2007 at 00:05

Yeah, but the camber is forced upon the suspension/wheels so there's only so much you can do to correct it.

M'ok

Thanks for the info.
